The paper examines the role of digitalization in the process of enhancing the cognitive and developmental environment of preschool education institutions. Focusing on early hildhood education, the author explores how the use of digital technologies can improve children, learning and development. The study analyzes the advantages of digitalization in preschool education, such as access to a range of educational resources, interactivity, individualized learning, and stimulation of children, creativity and imagination. It is proven that the use of digital tools such as computers, tablets, interactive whiteboards, multimedia presentations, and educational programs can make the learning process more meaningful and engaging for young children. The challenges and limitations associated with digitalization in preschool education are also investigated, such as the risk of excessive screen time, the need for qualified pedagogical staff and appropriate resources, and the impact on childrens social-emotional development. Recommendations are proposed for the effective implementation of digitalization in preschool education, including ensuring a balance between digital and non-technological teaching methods, increasing supervision of technology use, and teaching children digital literacy. The findings of this study contribute to a better understanding of how digital technologies can enrich the cognitive and developmental environment in preschool education institutions and provide recommendations for successful implementation of digitalization to enhance the quality of education for preschool-aged children.
